Peter Collingbourne b453cd64a7 Implement function type checker for the undefined behavior sanitizer.
This uses function prefix data to store function type information at the

Alp Toker 67b47ac0a7 Fix crash in cleanup attr handling
ResolveSingleFunctionTemplateSpecialization() returns 0 and doesn't emit diags
unless the expression has template-ids, so we must null check the result.

Also add a better diag noting which overloads are causing the problem.

David Majnemer ad51f1bc70 Sema: Diagnose global replacement functions declared as inline
This fixes PR17591.

N.B. This actually goes beyond what the standard mandates by requiring
the restriction to hold for declarations instead of definitions.  This
is believed to be a defect in the standard and an LWG issue has been
submitted.

Rafael Espindola ed452a0629 Add a missing getMostRecentDecl to ClassTemplateDecl.
llvm-svn: 193040
2013-10-19 21:06:31 +00:00
Rafael Espindola 7b56f6c3c2 Simplify some implementations of get*Decl.
* NamedDecl and CXXMethodDecl were missing getMostRecentDecl.
* The const version can just forward to the non const.
* getMostRecentDecl can use cast instead of cast_or_null.

This then removes some casts from the callers.

Richard Smith 3d8e97eda2 C++ modules: don't lose track of a 'namespace std' that is imported from a module.
llvm-svn: 192951
2013-10-18 06:54:39 +00:00
Richard Smith 2b9e3e396a Basic ODR checking for C++ modules:
If we have multiple definitions of the same entity from different modules, we
nominate the first definition which we see as being the canonical definition.
If we load a declaration from a different definition and we can't find a
corresponding declaration in the canonical definition, issue a diagnostic.

This is insufficient to prevent things from going horribly wrong in all cases
-- we might be in the middle of emitting IR for a function when we trigger some
deserialization and discover that it refers to an incoherent piece of the AST,
by which point it's probably too late to bail out -- but we'll at least produce
a diagnostic.

Alp Toker ae3a944a6e Fix missed exception spec checks and crashes
Delayed exception specification checking for defaulted members and virtual
destructors are both susceptible to mutation during iteration so we need to
swap and process the worklists.

This resolves both accepts-invalid and rejects-valid issues and moreover fixes
potential invalid memory access as the contents of the vectors change during
iteration and recursive template instantiation.

Checking can be further delayed where parent classes aren't yet fully defined.
This patch adds two assertions at end of TU to ensure no specs are left
unchecked as was happenning before the fix, plus a test case from Marshall Clow
for the defaulted member crash extracted from the libcxx headers.

Daniel Sanders 9469417064 [mips] Added -mfp64 and -mfp32 options.
These options specify 64-bit FP registers and 32-bit FP registers respectively.

When using -mfp32, the FPU has 16x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps
two single-precision registers).

When using -mfp64, the FPU has 32x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps
with one single-precision register and has an additional 32-bits).

MSA requires -mfp64.

Rafael Espindola 002667c32b On 32 bit windows, mangle stdcall and fastcall decls in clang.
This removes the dependency on the llvm mangler doing it for us. In isolation,
the benefit is that the testing of what mangling is applied is all in one place:
(C, C++) X (Itanium, Microsoft) are all handled by clang.

This also gives me hope that in the future the llvm mangler (and llvm-ar) will
not depend on TargetMachine.
